Benefits of technology

The patent describes a filter module that uses a triplexer to efficiently use a certain type of chemical compound. The technical effect is to improve the performance of the filter module.

Problems solved by technology

If a CA is applied, however, there is a problem in that three or more frequency bands cannot be support at the same time.
However, a conventional support module, such as those of FIGS. 1 and 2, is problematic in that a CA cannot be performed on the B1 band frequency, the B25 band frequency, and the B3 band frequency at once.

Abstract

A filter module includes an antenna, at least one filter configured to transmit a signal corresponding to a frequency of a predetermined band, and at least one amplification module connected to the filter and configured to amplify a signal. The filter includes a triplexer.

Description

CROSS REFERENCE TO RELATED APPLICATION[0001]The present application claims the benefit of Korean Patent Application No. 10-2015-0126487, filed in the Korean Intellectual Property Office on Sep. 7, 2015, the entire contents of which are incorporated herein by reference.BACKGROUND OF THE INVENTION[0002]1. Technical Field [ 0002 ] The present invention relates to a filter module including an antenna, at least one filter configured to transmit a signal corresponding to a frequency of a predetermined band, and at least one amplification module connected to the filter and configured to amplify the signal, wherein the filter includes a triplexer.[0003]2. Description of Related Art[0004]Smart terminals become explosively popular worldwide. In particular, since the year 2011, the use of Long Term Evolution (LTE), that is, a new mobile communication standard, and the number of countries in which LTE is used are suddenly increased. In LTE, a method for allocating various frequencies to communi...
